*According to Unesco (2013), Italian Braille uses the old French parentheses ⠶⠀⠶ as square brackets. According to the Unione Italiana Ciechi di Legnano, those are used for parentheses; square brackets are not given. And according to the Unione Italiana dei Ciechi e degli Ipovedenti, square brackets are ⠷⠀⠾; Unesco and the Unione agree on the assignment of ⠢⠀⠔ to the parentheses, as in the chart above, and the Unione has ⠯⠀⠽ for braces. (⠯ç and ⠽y are not part of the Italian alphabet.) However, the Unione specifies than the symmetrically paired brackets are mathematical notation, so it may be that the old, generic ⠶⠀⠶ is the convention for either parentheses or square brackets in non-mathematical text.
